Hi, I found a couple of drivers in this forum for nokia 5110 lcd but all of them were mainly txt drivers. So I wrote this one that implements graphical functions like drawing pixels, lines, boxes, circles, bars...
It uses a video memory map, so you can have txt and graphics at the same time. First you "draw" everything you want to show in that memory and then dump it to the lcd.
I hope you enjoy it!.
I uploaded a video of it to youtube: https://www.youtube.com/watch?v=x6TdIBKR3N4&feature=youtu.be
